yes had period on the 15th october
if you just had your period on 10.15.11 you probably would want to wait before you try and determine if your pregnant.. if you mean you had a period before october 15 then had bleeding on 10.15.11 that was light and not as long as your regular period i would take a test and see. but it depends on what you mean.
do u mean, 15 oct was the day you had your period ?
